VENTlLATlNG-SPOUT FOR VESSEVLS.

SPECIFICATION forming part of Letters Patent No. 718,487, dated January 13, 1903.

Application filed June 30, 1902. Serial No. 113,868. (No model.)

D near its base, and the space between D and To all whom, it may concern.-

Beitknown thatWe,ABBOTAUGUSTUS Low, residing at Horseshoe, county of St. Lawrence, State of New York, and JAMES MILNOR HICKS, residing at Summit, Union county, New Jersey, citizens of the United States, have invented jointly new and useful Improvements in Ventilating-spouts for Vessels, of which the following is a specification.

Our invention relates to ventilating pouring-spouts for vessels and to means for admitting air to the vessels automatically without disturbing the outward flow of the fluid contents thereof while pouring; and to this end it consists in certain elements fully specified hereinafter, and claimed at the end of this schedule.

In order that those skilled in the art to which our invention appertains may understand, construct, and use our invention, we will proceed to describe it, referring to the drawings herewith, in which- Figure l is a longitudinal central section of a vessel with our invention applied thereto. Fig. 2 is a top view of same, partially broken away to show the internal structure.

A is the body of the vessel.

B is the mouth of the vessel proper, the walls of which are screw-threaded upon their exterior.

C isa cap which is screwed upon the threads upon the walls of the neck at O D is a flange turned inward from and above the screw portion 0 of the lower barrel of the cap.

C is a screw-threaded portion of the cap 0 at its top and receives a sealing-cap E, screwthreaded at E, and has a sealing F within it.

D is an internal lining or shell shaped similarly to cap 0, but not screw-threaded. Its upper part D rises to the level of the top of the part 0 of the cap and is of much smaller diameter than the part 0, leaving a space between the two. At the bottom of shell or lining D a flange is turned outwardly and extends under the part D of the cap 0 and embraces a packing-ring G, so that when the cap 0 is screwed down upon the top of the walls of neck B the joint is packed tightly, and when the sealing-cap E is screwed down upon the top of the parts D and C a tight closure is made and the vessel is tightly sealed.

e e are openings made through the lining O is put in communication with the interior of vessel A.

The vessel being filled with fluid to the proper height, when it is desired to empty it the sealing-cap E is removed and the vessel turned on its side. The fluid will pour out through the spout D, and the air will enter the vessel through the space between D and O and the holes e, which are uppermost. The holes e are small in area and quite few in number, usually about three, so that two air-holes e will be uppermost to admit air to the vessel while pouring and but one at the lower point to discharge fluid, which will be insignificant in operation.

The operation of our invention as above stated is most satisfactory.

We have shown our invention as applied to a form of cap patented to us in part at a previous date; but we do not confine ourselves to a cap attached to a vessel separately; but we intend to apply our invention to vessels solidly, with only a single closing cap, as E, but with the internallining D and D.

Having now fully described our invention and the manner in which we have embodied it, what we claim as new and as our invention, and desireto secure by Letters Patent, is-

In a discharge-spout for vessels the combination consisting of an outer barrel; an inner lining; means for attaching the same to a Vessel; and means for closing the mouth of said spout, and for opening it in use; the mouth of the inner lining being of smaller area than the area of the mouth of the outer barrel, the base of the inner lining being perforated to permit air to pass between the said barrel and the said lining, and into the body of the vessel at the same time the contents of the vessel are being discharged all constructed, arranged and combined to operate as and for the purposes specified.

In testimony whereof we have respectively each signed our names to this specification, in the presence of two subscribing witnesses, this 13th day of June, 1902.
